Description
Technical Field
The invention belongs to the technical field of cigarette products, and particularly relates to a non-combustion tobacco product heated by a single-point flame heater.
Background
Along with the improvement of health consciousness, in order to properly reduce the harm of tobacco products to human health, new heating non-burning tobacco products are developed and designed, and the products have the characteristic of heating tobacco shreds instead of burning tobacco shreds, so that harmful components generated by high-temperature burning and cracking of tobacco can be reduced, the release amount of chemical components of main stream smoke is greatly reduced, and the tobacco products are promoted to a certain extent.
In the prior art, according to the heating mode, heating non-combustion type tobacco products mainly comprise electric heating type tobacco products, carbon heating type tobacco products, physicochemical reaction heating type tobacco products and the like. The electric heating type tobacco product is represented by Accord, heatbar, IQOS developed by the Feimo company, and consists of an electric heater and a matched cigarette, when a consumer sucks, the consumer needs to use a special electric heater to suck, and the electric heating type tobacco product has great difference from the traditional cigarette sucking mode, is inconvenient to use and has lower consumer acceptance. Carbon-heated tobacco products are represented by Eclipse from reynolds corporation, which heat tobacco filler by combustion at the carbonaceous heat source end to produce smoke, but have the disadvantages of difficult ignition of the carbonaceous heat source, large carbon smell, and the like. In terms of the products of the thermal type of the finishing reaction, it is typical to, for example: patent CN200980133308.0 utilizes the exothermic heat of crystallization of crystallizable substances such as sodium acetate trihydrate, mirabilite, and/or magnesium nitrate hexahydrate in supersaturated solutions to heat a nicotine solution to produce a nicotine aerosol. In patent US20120006342, tobacco shreds added with calcium oxide and high-concentration nicotine are mixed with pyruvic acid, and the tobacco shreds are heated by using heat generated by an acid-base reaction to form smoke. The CN200980102589.3 patent utilizes a great amount of heat generated by oxidation-reduction reaction of metals such as iron, aluminum, magnesium, lithium, cobalt, platinum, palladium, copper and the like and oxygen-containing strong oxidants such as potassium permanganate, manganese dioxide, lead tetraoxide, barium peroxide, bromate, chlorate and the like under specific trigger conditions (heating or oxygen) to heat the tobacco shreds, thereby generating smoke. Patent EP 0371285 mentions the reaction of metal oxides or anhydrous metal sulphates with water as a heat source. However, in general, the heating of non-combustion tobacco products by physical and chemical reactions has poor control of heat and relatively complex process, so that practical popularization and application are very limited.
In a word, the tobacco type is limited to be different, and the corresponding heating modes and heating appliances have larger differences, so that the design of new cigarette products still has very important practical significance for better adapting to the demands of people on various tobacco products.

The controller is connected with the battery and is powered by the battery; meanwhile, the battery is respectively connected with the fuel delivery control valve and the igniter through circuits to provide power for the fuel delivery control valve and the igniter;
the fuel chamber is used for supplying fuel, typically liquid butane, liquid propane or liquefied petroleum gas, to the flame spray head.
In practical design, a sensor can be further arranged at the bottom of the heating cavity, and the sensor can be respectively connected with a power supply and a controller through a circuit and is used for sensing the insertion of cigarettes and the beginning and ending of suction.
In a specific design, the specification of the inner cavity of the heating cavity is adapted to the specification of a heat-conducting cigarette product, the diameter of the inner cavity is generally 5-9 mm, and the length of the inner cavity is 35-80 mm.
In the specific design, the distance between the flame spray head and the outer wall of the heating cavity is 1-4 cm, so that the flame temperature is better ensured to be better transferred and heated; after the flame spray head is started, the flame height sprayed by the flame spray head is 0.5-3cm, and the flame temperature is 250-500 ℃.
In the practical design, the outer wall of the heating cavity can be provided with heat conduction holes corresponding to the flame sprayed by the flame spray head, so that the flame can directly heat the heat conduction cigarettes in the heating cavity conveniently; the shape of the heat conducting hole can be designed into a round shape, a square shape, a triangle shape and the like so as to adjust flame seedlings, thereby ensuring that the heating area is more uniform.
In a specific design, the heating position of the flame nozzle relative to the heating cavity is fixed or movable, specifically:
Aiming at a fixed structure (namely, the heating position of the flame spray head relative to the heating cavity is fixed), a cigarette moving manual shifting piece is arranged in the heating cavity in a matched manner and is used for adjusting the heating position of the heat-conducting cigarette in the heating cavity; the manual pulling piece for moving the cigarettes extends to the outside of the single-point flame heater shell, so that the heated position of the cigarettes can be moved manually from the outside of the shell;
for the movable structure (i.e. the heating position of the flame spray head relative to the heating cavity can be changed), the structure can be designed into a manually movable structure or an automatically movable structure, in particular:
aiming at the manual moving structure, the flame spray head is of a manual moving structure which moves along the outer wall of the heating cavity, and when the manual moving structure is specifically designed, the bottom of the flame spray head is provided with a manual shifting piece for moving the flame spray head, and the manual shifting piece can be manually moved from the outside of the single-point flame heater shell, and the heating of different parts of the heat-conducting cigarette is realized through the manual movement of the flame spray head;
Aiming at the automatic movable structure, the flame spray head is a movable structure which is controlled by the controller and can automatically move along the outer wall of the heating cavity, the bottom of the flame spray head is provided with a moving device connected with the controller, and the automatic movement of the flame spray head is controlled by the controller to heat different parts of the heat-conducting cigarette.
When the specific suction is used: when the heat-conducting cigarette is inserted into the heating cavity, the sensor senses the cigarette insertion and triggers the controller to start; when the smoking is started, the sensor activates the igniter and the fuel delivery control valve through a preset program by triggering the controller, so as to activate the flame spray head to heat the cigarettes; when the suction is stopped, the sensor transmits a trigger signal to the controller again, and the controller closes the igniter and the fuel delivery control valve through a preset program, so that the flame spray head is closed; in the sucking process, along with the change of the number of the sucking ports, the heating position of the cigarette can be adjusted by manually moving the cigarette or manually moving the flame spray head, or the controller automatically moves the flame spray head to automatically heat different parts of the cigarette according to a preset program. When smoke generated in the sucking process passes through the bead explosion section of the composite filter tip, the bead explosion section has the dual functions of flavoring and cooling, the solvent wrapped in the bead explosion section can be evaporated to play a role in cooling, and the volatilization of the essence and the spice in the bead explosion section can be used for flavoring the main stream smoke, so that the smoke quality is improved; when the flue gas passes through a cooling section made of the polylactic acid film, the polylactic acid film can undergo glass transition (the glass transition temperature is generally about 60 ℃), and absorbs heat, so that the temperature of the flue gas is effectively reduced; the smoke after cooling and flavoring is finally filtered by the tow filtering section to further filter harmful components, and finally enters the mouth of the smoker, thereby meeting the physiological and psychological needs of the smoker.
In general, the main advantages of the present application are represented in the following aspects:
